DISCOVERY OF 28 OPEN CLUSTERS WITH GAIA DR3

In this work we searched for open clusters in the fields of star-forming regions in the Galaxy using the HDBSCAN applied to the astrometric data from the Gaia DR3 catalog. We identified 28 new open clusters, of which the real existence is supported by the membership probability determined from astrometric data and by the presence of cluster sequences in their color-magnitude diagrams, which allows for a reliable isochrone fit. Of the open clusters identified, 3 are younger than 50 Myr, 19 are of intermediate age, and 6 are old clusters. The clusters have apparent radii ranging from 3 to 20 arcmin. For all clusters, we estimate mean proper motion, mean parallax, and fundamental parameters considering the member stars for each cluster. One of the discovered clusters has a distance of 10 kpc and a log(age) ≈ 10.1, making it one of the most distant and oldest cataloged open clusters.
